Geo-Location Estimate (GLE) Sensitive Physical Access Control Methods of Operation

ABSTRACT

A method operates a server that is coupled to a network controlling door actuators at physical geo-locations. The server receives through a wireless communication network a request to enable physical access at a portal using a secure channel and a geo-location estimate from a mobile device. A circuit of the mobile device receives radio signal magnitude, phase, and power from at least one transmitter and authentication input from a user interface. Dual secured communications paths protect the server on its separately provisioned request channel and actuator command channel. Each legacy electronically controlled access portal is enabled to support smartphones without installing a replacement multi-band radio frequency reader at the geo-location.

BACKGROUND OF THE INVENTION Technical Field

The present invention relates to physical access control and identity management, access control mechanisms for managing physical “points of service”, physical access portals, or other physical resource access control methods and apparatus, wireless door actuators, locks, and security systems.

Description of the Related Art

Within this application the term physical access portal (portal) refers to a control point or boundary through which a person or vehicle or object can traverse if permitted or be denied transit whether it is an entrance or exit from or to a structure or area or region. Non-limiting examples of portals are doors, gates, lifts, elevators, bridges, tunnels, tubes, vehicles, chair, tow, canal lock, hatch, or wormhole.

As is known, mobile devices including wearable devices, communicating via the cellular telephone network, also include geo-location services by detecting signal strengths and phases from Global Positioning System (GPS) satellites, Wi-Fi Access Points, Cellular Base Stations, Bluetooth beacons, and other non mobile signal emitters which have fixed location. As is known, mobile devices may include circuits for image capture in 2D or 3D in visible and non-visible spectrum and comparison with stored images.

As is known, mobile devices including cellular phones and wearables often include NFC, RFID, and Bluetooth transceivers which can connect with security system readers.

Conventional access control systems depend on one or at most two factors of authentication. Usually a key or key card is a resonator energized by a reader. The reader is hard wired to a server which verifies access time and location of a particular door or entry. Upon presentation of the key card, an identity is transmitted to the server which operates a door lock/unlock solenoid through a wire or network. Mere possession of the key or key card enables access during certain times.

A Key Card is often lost by the user and needs to be replaced. This has a cost associated with it. The user needs to remember to bring the “key card” with them. They often forget and a temporary card needs to be issued. The key card is not always important to the user so they neglect it.

As is known in the industry there is a desire to replace the key card with a personal mobile phone because this eliminates an item that the user must carry—and her personal phone is an item that is important to the user so she takes constant care to retain it.

Mobile phones and other electronic devices do not today typically have an NFC or RFID built in. Many however have Bluetooth function built in. There is a desire to use this function to open the door and many products have been introduced to “read” a Bluetooth signal at the door. This solution, however, requires installation of new hardware at the door, which can be costly.

Another conventional access control system depends on knowledge of a pass code, phrase, numerical combination, or answers to questions. Knowledge of the shared secret enables access during certain times. Some systems use a combination of a NFC reader with a shared secret. Because the channels are essentially bidirectional the shared secret can be stolen.

Alternately, a cryptographic key code which is pseudo-randomly generated by a dedicated dongle has the problem of delivery to an authorized user and retention by the authorized user. It can be left behind, lost, or stolen.

As is known, physical access to the server compromises all security schemes.

What is needed is increased flexibility, granularity, and heightened security for access control. What is needed is a method to utilize mobile wirelessly connected personal devices to open doors without replacing the legacy hardware at the door

BRIEF SUMMARY OF THE INVENTION

A system includes a server coupled to a plurality of wirelessly connected mobile personal devices. The server receives through a wireless communication network a request to enable physical access at a portal using a secure channel and a geo-location estimate from a mobile device. A circuit of the mobile device receives radio signal magnitude, phase, and power from at least one transmitter and authentication input from a user interface. Dual secured communications paths protect the server on its separately provisioned request channel and actuator command channel. Each legacy electronically controlled access portal is enabled to support smartphones without installing a replacement multi-band radio frequency reader at the geo-location.

The mobile device transforms location data from among Global Positioning System satellites, cellular base stations, WiFi Access Points, Bluetooth beacons and other radio emitters with known locations into a Geo-Location Estimate coordinate with enough precision to uniquely identify a specific portal on a specific floor of a structure.

Upon user request or launched by a proximity trigger, an apparatus verifies a user identity, determines a geo-location estimate coordinate, and through a private channel transmits at a certain time to a access control service a one-time open command.

An access control server, securely coupled to a door control actuator, determines that a verified user is allowed access according to a rule. An exemplary rule enables physical access to an authenticated user within a range of time at a location when a one-time open command is received via a private channel.

A system couples legacy access controlled doors to modern wireless devices. A smartphone application obtains a Geo-Location Estimate (GLE) coordinate; the smartphone authenticates a user identity (fingerprint, passphrase, camera, etc.), transmits an access control request via a cellular or WiFi network to the server controlling the access, using a public/private key to protect the server and the facility from attack.

An access control server is coupled to a cellular network or Internet for access requests and also coupled to the equipment that grants access. The user and his location is authenticated for approved access at the GLE coordinate. A door control signal is transmitted to the door actuator. Each operation will result in a unique request due to the timestamp and prevents recording and playback.

Legacy Bluetooth, NFC, RFID and other radiofrequency (RF) readers may be operated in parallel and/or eventually retired at end of life. A physical access control server determines whether a GLE coordinate presented by a mobile device is within a specified range of the Geo-Location coordinate stored for each portal.

The physical access control server is connected to at least one physical access portal and transmits a command to enable or suppress access upon receiving and verifying a request from a mobile device via a wireless network. The wireless network may use Internet Protocol. The wireless network may use cellular data communication protocols.

An app is installed from a secure store to a mobile device. A public/private key pair is generated during download, installation, or launch for each instance of an installed app. A public/private key pair may be used for app communications with the access server. A digital certificate may be used for transport layer encryption.

The access server can be provisioned within the secured premises or the access server can be provisioned by a shared service in the cloud.

The access server may be reached via one or more intermediate servers or directly. The app optionally requires authentication of a user by the facilities of the wireless device: by passcode, fingerprint, camera, biometric, etc. The app receives and encrypts a GLE coordinate upon request. Through the cellular network, a request is transmitted to a server to actuate a door access control with a virtual card key. The request is authenticated to a specific device and to a specific user. Each transmitted request is unique.

The server receives the cellular data and decrypts an access request using its stored keys. The user id is verified for access control to time and place. The door closest to the GLE location of the devices is identified. Using a separate channel, e.g. wire, WAN, TCP/IP or other network, a signed command is transmitted to the door control unit for a limited period of time.

CONCLUSION

The invention is easily distinguished from conventional electronic access control systems which cannot economically migrate to make use of smartphones and which have physical security weaknesses. The present invention uses cryptographically secure protocols to address the limitations of key cards such as: loss of key cards, limited compute power within an inexpensive key card, and detection of attacks.

The invention is easily distinguished from systems which require retrofitting legacy doors with new radio frequency hardware. The invention is easily distinguished from any system that requires expensive dedicated high compute circuits to be distributed and carried by users. The invention is easily distinguished by enablement of visitor or occasional user access by offering an over the air installation.

The techniques described herein can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them. The techniques can be implemented as a computer program product, i.e., a computer program tangibly embodied in a non-transitory information carrier, e.g., in a machine-readable storage device, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers. A computer program can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.

The invention is distinguished by preventing a third party from measuring signals at the location of the door to record and decode a signal between the smartphone and the door. Each instance of the App authenticates a request for a geo-location area for an identified user. The channel for conveying requests is diverse from the channel for conveying the door access command. Both request and command are intrinsically geo-location and time-limited unlike a physical key or key card which typically of themselves do not expire.

Method steps of the techniques described herein can be performed by one or more programmable processors executing a computer program to perform functions of the invention by operating on input data and generating output. Method steps can also be performed by, and apparatus of the invention can be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Modules can refer to portions of the computer program and/or the processor/special circuitry that implements that functionality.

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks.
